There is still no evidence that any federal laws were broken.
You must not know about the federal records act of 1950 and the national archives and records regulations of 1995. NARA (National Archives and Records Administration) adopted regulations in 1995 which required the preservation of official e-mails created on non-official accounts. The Archivist interpreted the Federal Records Act to apply to e-mail records and further provided that “[a]gencies with access to external electronic mail systems shall ensure that federal records sent or received on these systems are preserved in the appropriate recordkeeping system . . .” So as early as 1995, all federal agencies were required to preserve official e-mails, including those created or maintained on “external electronic mail systems.”
Later NARA regulations merely clarified this requirement. In 2009, after a Government Accountability Office report indicated that certain agencies had lax e-mail practices, the NARA adopted new regulations that provided that any emails created on private e-mail accounts must be preserved. But that regulation merely restated, in perhaps slightly different language, what the 1995 regulation had already mandated, requiring that “[a]gencies that allow employees to send and receive official electronic mail messages using a system not operated by the agency must ensure that Federal records sent or received on such systems are preserved in the appropriate agency record keeping system.”
Now just saying that the other employees with a .gov email address had the emails archived does not meet the criteria of the law. What if other government employees also used personal email? Then there would be no official government archive of the email. What about her official emails to foreign heads of state? Those were not archived either. What about official emails to non .gov addresses in the US? Just these questions show that she did not follow the laws and regulations that were established before and during her time in office.
